This Circular chain knocker is suitable for use in PVC (ABS) pipes because it has no hard metal tips.
Perfect for the fast removal of hard incrustations such as urine scale, lime scale, cement or tile grout. The knocker is also well suited for removing pipe blockages caused by root intrusion.
The centrifugal force of the circular chain acts perpendicular to the axis over the full circumference of the pipe, so the chain is capable of cleaning damaged or delicate pipework.
In contrast to the conventional chain knocker, this prevents the pipe wall from being subjected to individual blows, and the chain works over the full circumference of the pipe on the pipe wall.
Sizes range for pipe diameters from 50mm (2”) to 200mm (8”)
This product is made from stainless steel links, which mount easily to an 8mm (5/16") ,10mm (3/8") & 12mm (1/2″) flex shaft, with set screws.
